Prefer stronger algorithms in algorithm negotiation.
Prefer diffie-hellman-group14-sha1 (2048 bit) over
diffie-hellman-group1-sha1 (1024 bit).
Due to meet-in-the-middle attacks the effective key length of
three key 3DES is 112 bits. AES is stronger and faster then 3DES.
Prefer to delay the start of compression until after authentication
has completed. This avoids exposing compression code to attacks
from unauthenticated users.

Dropbear for Debian ------------------- This package will attempt to listen on port 22. If the OpenSSH package ("ssh") is installed, the file /etc/default/dropbear will be set up so that the server does not start by default. You can run Dropbear concurrently with OpenSSH 'sshd' by modifying /etc/default/dropbear so that "NO_START" is set to "0" and changing the port number that Dropbear runs on. Follow the instructions in the file. This package suggests you install the "ssh" package. This package provides the "ssh" client program, as well as the "/usr/bin/scp" binary you will need to be able to retrieve files from a server running Dropbear via SCP. Replacing OpenSSH "sshd" with Dropbear -------------------------------------- You will still want to have the "ssh" package installed, as it provides the "ssh" and "scp" binaries. When you install this package, it checks for existing OpenSSH host keys and if found, converts them to the Dropbear format. If this appears to have worked, you should be able to change over by following these steps: 1. Stop the OpenSSH server % /etc/init.d/ssh stop 2. Prevent the OpenSSH server from starting in the future % touch /etc/ssh/sshd_not_to_be_run 3. Modify the Dropbear defaults file, set NO_START to 0 and ensure DROPBEAR_PORT is set to 22. % editor /etc/default/dropbear 4. Restart the Dropbear server. % /etc/init.d/dropbear restart See the Dropbear homepage for more information: http://matt.ucc.asn.au/dropbear/dropbear.html
